Abstract. Irawati W, Pinontoan R, Mouretta B, Yuwono T. 2021. The potential of copper-resistant bacteria Acinetobacter sp. strain CN5 in decolorizing dyes. Biodiversitas 23: 680-686. Bacteria with multi-resistance to copper and dyes may be employed bioremediation dye waste more effectively than physical or chemical remediation. This study aims at determining the effect addition various textile ...

Background and Objective: Acid dyes are synthetic organic compounds with complicated chemical structures which their treatment are difficult and costly. Discharchig of these dyes into the environmen causes harmful effects on ecosystem and water quality. In this study efficiency investigation of photo-fenton process in removal of acid green 20 dye from wastewater of textile industries was assess...

BACKGROUND Vat dyes are the class of dyes used in textile dyeing in Abeokuta, South Western Nigeria. While some dyes (including vat dyes intermediates) have been associated with adverse effects on manufacturer's health, there is paucity of data on effects of occupational exposure to vat dyes among end users, such as those involved in textile dyeing and finishing. AIMS AND OBJECTIVES To invest...

This thesis examines different classes of dyes, the processes they require, their use on different textiles, and their potential effects on the environment. Additionally, experiments with natural dyes were conducted and documented. Natural berries, roots, and other dyestuffs were collected and used to dye both natural and synthetic textiles. Through research and experimentation, the different t...

In recent years, the textile industry must go towards developing of new technologies to reduce the energy and water consumption. The use of microwave in textile wet processing is one way for this purpose. The advantages of microwaves, which it is use much less liquid, they can exhaust or save dyes and leave no waste of liquid dye compared to conventional methods. Microwave dyeing has other adva...

Present study was designed to evaluate the effects of chemicals used in textile dyes on the health of occupationally exposed workers. The various blood biochemical parameters of a total of 62 male textile workers (2045 years of age) involved in the dyeing processes for a period of six months to 20 years and 50 non-industrial workers were compared to assess the health of industrial workers. The ...
